Rain watch: Chances look good for showers later today

It’s now been one month since Houston got a good soaking, but we should break that dry streak today.

That’s because a disturbance in the upper levels of the atmosphere, coupled with a cold front, should bring enough of a spark to knock some of the moisture out of the atmosphere in the form of rainfall.

The latest models suggest most of the Houston area should get about one-half to 1 inch of rain today and tonight.

There is a possibility of scattered rain showers this morning, and by noon rain chances rise to above 60 percent for the region. Expect the rain to taper off by about midnight, giving way to a breezy and cool day on Wednesday.

Forecasters with the National Weather Service expect rain chances to to be lower southwest of Houston, and end somewhere between the Bayou City and Corpus Christi. This is because of the “cap” on the atmosphere, where a warm layer above the surface inhibits the condensation of moisture in the air, should erode much less there.

But for most of the Houston region today and tonight should bring a decent amount of rain that will set the stage for a beautiful second half of the week.
